This can result in a full compromise of the confidentiality, integrity, and availability of the system.","published":"2021-09-14T12:15:10.000Z","lastModified":"2026-06-17T04:00:41.000Z","status":"Modified","sourceIdentifier":"cna@sap.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-78"],"affected":["sap/netweaver knowledge management xml forms"],"epss":{"score":0.03155,"percentile":0.87872,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.16%).
